Hallo Zusammen,
ich habe drei SDM120 verbaut, die ich über einen Modbus USB Stick mit dem Raspberry Pi verbunden sind.
Mit dem Modbus Adapter kann ich alle drei mit der jeweiligen Slave ID auslesen.
Ich beschäftige mich in letzter Zeit mit Node-Red und möchte nun von dort aus, die Daten abrufen und in ein Modbus TCP Register schreiben.
Leider erhalte ich folgende Fehlermeldungen, sobald ich mehrere Slave ID´s abfrage.Client -> fsm broken state after init Get More About It By Logging Serial@/dev/ttyUSB0:9600bit/s default Unit-Id: 1Ich weiß ehrlich gesagt nicht, wieso er mir hier immer die 1 anzeigt, obwohl ich eine 10, 11, 12 eingestellt habe.
Mein Flow:

@malaus Du solltest den Titel editieren und erwähnen das es sich um "Node-Red" handelt.
-
@malaus sagte in Node-Red Modbus mehrere Slave ID´s abfragen:
- Wenn Du einen Flow postest - dann bitte in Code-Tags da ansonsten nicht importierbar da die Forensoftware bestimmte Zeichen zur Formatierung verwendet.
- Falls Du Modbus Nodes und den Adapter verwendest, dann weiss ich nicht, ob das zu Konflikten kommt, Wenn Du über den iobroker Adapter kommunizierst, dann brauchst Du doch die Node-Red Nodes nicht mehr.
-
@mickym Danke für den Hinweis. Habe es im ersten Post korrigiert.
Hier wäre auch ein Screenshot:
Den Modbus Adapter muss ich stoppen, sonst kann ich keine Daten abrufen.
Weshalb ich das ganze über NodeRed machen möchte, weil ich die Daten anschließend an Modbus TCP schicken möchte. Wenn ich das über den Modbus Adapter mache, muss ich ein Javascript schreiben und dort die Werte an die neue Modbus Instanz übertragen. Und da ich zurzeit viel mit NodeRed ausprobiere, dachte ich es wäre doch schöner das ganze hier umzusetzen.
Was ich aber noch nicht verstehe ist, dass ich diese drei Geräte über den Modbus Adapter erreiche und bei NodeRed nicht bzw. dort immer nur eins gleichzeitig. Liegt das vielleicht daran, dass ich nur eine aktive Verbindung aufbauen darf?
-
@malaus Aber du kannst doch die Datenpunkte über des Modbus Adapters in Node-Red auslesen und beschreiben. Dafür brauchst Du die Modbus Nodes nicht. Und musst auch nichts programmieren.
-
@mickym ums programmieren gehts mir nicht. Ich wollte es einfach ausprobieren beides in NodeRed umzusetzen. Klar, ich kann die Daten auch von ioBroker ins NodeRed holen und diese dort weiterleiten an Modbus TCP.
Es wundert mich halt noch immer, wieso das mit dem Modbus Adapter funktioniert aber nicht mit NodeRed. -
@malaus Wie gesagt kann es sein, dass ich da was beisst.
Vielleicht musst den Adapter mal deaktivieren und schauen, ob es sich dann anders verhält. Ich kann Dir sonst leider nichts dazu sagen - weil alles was mit Schnittstellen zu Geräten zu tun hat, ich nicht nachvollziehen kann. -

Was ich aber noch nicht verstehe ist, dass ich diese drei Geräte über den Modbus Adapter erreiche und bei NodeRed nicht bzw. dort immer nur eins gleichzeitig. Liegt das vielleicht daran, dass ich nur eine aktive Verbindung aufbauen darf?
Aber er liest doch Daten aus.
Der Flow kommt mir recht seltsam vor. Den drei SDM hast Du doch unterschiedliche Adressen vergeben? Ich würde sie nacheinander mal einzeln und auch nur einen DP abfragen. Dazu würde ich nicht das Flex Getter verwenden. Ich würde in kleinen Schritten vorgehen. Um wieder Dezimalzahlen zu bekommen gibt es den BufferParser.

@garf sagte in Node-Red Modbus mehrere Slave ID´s abfragen:

Das war aus einem Versuch mit nur einer Geräten ID.

Dazu würde ich nicht das Flex Getter verwenden. Ich würde in kleinen Schritten vorgehen. Um wieder Dezimalzahlen zu bekommen gibt es den BufferParser.
Wieso nicht das Flex Getter benutzen?
Ich hab das ganze mal so ausprobiert:
Hier schicke ich eine Anfrage an das Gerät 10. Das funktioniert. Baue ich nun in die Funktion eine weitere Anfrage mit einer anderen Geräte ID ein, erhalte ich eine Fehlermeldung.
Baue ich hingegen eine zweite Funktion für das Gerät 11 und drücke nacheinander, funktioniert es.
Wenn ich jetzt einen weitern Schritt gehe und das ganze so baue, geht es auch:
Obwohl ich hier eine Dauerschleife eingebaut habe...Bedeutet für mich, dass ich das so bauen muss, das erst die Anfragen an eine andere ID geschickt werden darf, wenn gerade keine Kommunikation stattfindet. Vermutlich ist das dann so im Modbus Adapter eingebaut.
Jetzt stellt sich mir die Frage, wie bekomme ich mit, dass der Lauf mit der Abfrage einer ID beendet ist?
Ich habe das ganze ja als JSON gebaut und frage durch ein Split nacheinander alles ab.
Alles in eine JSON packen und nacheinander abfragen lassen, geht nicht. Vermutlich wird ein Delay zw. den ID´s benötigt.Vielleicht mit einem Zähler, der die Nachrichten am Ende liest und sobald die Menge der Nachrichten erreicht ist, aktiviert es die nächste ID. - funktioniert nicht wie gedacht.
Meine Lösung:
Ich frage bei "JSON ID11" und "JSON ID12" ab, welches topic zuletzt abgefragt worden ist.
Ist es das letzte, kann gestartet werden.
So kann ich nun alle drei Geräte ID´s abfragen.@mickym
hast du vielleicht eine Idee, wie man das in NodeRed umsetzen könnte?
vielleicht gibts hier eine elegantere Lösung? -
@malaus Ich mach Die mal einen Flow , wie es evtl. dann gehen könnte. Kann es sein, dass die Obkelte immer gleich ausschauen und sich nur die ID ändert? - Wenn ja dann poste mir doch mal bitte EIN Objekt - wo man nur die ID austauschen muss. Wenn sich die Objekte sonst noch unterscheiden halt das ganze Array mit den 3 Objekten - hier in Code Tags.
-
@mickym
Die Objekte, die ich abfrage sind bei allen drei Geräten gleich. Sie unterscheiden sich nur von der Geräten ID (unitId).
Ich weiß, du wolltest nur eins, ich hab dir aber mal zwei kopiert, damit der Unterschied bzw. das was gleich ist, ersichtlicher ist.

@malaus So ich habe ja kein Modbus - und im Prinzip sendest Du ja nicht nur ein Nachricht in dieses Flex Getter, sondern wie ich das sehe 21 * 3 - und dass da die Hardware aus dem Tritt kommt, das wundert mich ehrlich gesagt nicht.
Mir ist auch nicht klar, warum Dein Array oder Deine Objekte soviele Informationen haben (aber vielleicht ist das nur ein anderer Output), wenn Du dann bei Deinem ReadModbus dann die meisten Informationen wieder wegschmeisst.
So hier ein paar Optimierungsvorschläge:
Nun wie bekannt, bin ich kein Freund von Codierung und function Nodes, wenn es nicht sein muss. Wenn es also um reine Änderungen der payload geht - solltest Du es in meinen Augen vermeiden - dafür gibts die Change Nodes. Wie sowas geht habe ich Dir in meinem Flow mal gezeigt.
Als erstes habe ich festgestellt, dass Du in Deiner split Node hier msg.parts eingetragen hast - ich weiß das Feld ist rot - aber Du kannst es ignorieren, weil Du ja kein Objekt aufsplittest, sondern ein Array. Insofern gilt das für Dich gar nicht.
So ich musst natürlich diese Modbus Flex Getter Node simulieren - deshalb hab ich nur mal in etwas das angenommen, was vielleicht aus dieser Node rauskommen könnte anhand der Screenshots die ich gesehen habe.
Du hast ja auch bereits schon viel richtiges gesagt und festgestellt:
Die einfachste Variante ist wohl einfach wirklich die Nachrichtenrate mit einer delay Node zu begrenzen, um der Getter Node genügend Zeit zu geben bzw. der Hardware genügend Zeit zu geben, die Anfragen zu kompletieren. Die werden halt nicht selbst gepuffert. (dann kommt man auch ganz ohne function Nodes aus).
Die 2. Variante entspricht in etwa der, die Du jetzt hast, wobei - da alles gleich ist bis auf die ID - ich diese 3 Flows halt zusammengefasst habe. In dem Fall musst Du wirklich mit einer function Nodes arbeiten, da diese einen Kontext hat, der durch das Array der IDs, durch die Du iterieren willst speichern kann und einen zugrhörigen pointer. Mit jeder payload wird der pointer wieder zurückgesetzt.
Der Code ist nicht kompliziert - aber ist halt wirklich eine der Fälle, wo eine Function Node Sinn macht und ein paar JS Kenntnisse haben sollte.
if (msg.payload) { context.set("data",msg.payload); context.set("pointer",0) } var array = context.get("data"); var pointer = context.get("pointer"); pointer ++; if ( pointer <= array.length) { msg.payload = array[pointer - 1]; context.set("pointer",pointer); return msg; }Wie gesagt woher diese Mengen Adressen etc. herkommen das weiss ich alles nicht und muss es auch nicht wissen. Ich hab nur einfach das was Du mit Deinen Function Nodes machst, mit Change Nodes vereinfacht.
Was aus der Getter Node rauskommt ist natürlich reine Fantasie. msg.payload = { data : [0,0], buffer: Buffer.alloc(3) } msg.modbusRequest = { address : 99, quantity : 2 } if (msg.parts.index === msg.parts.count -1) return [msg,{payload:true}];Ich hab jetzt halt nur gewartet bist das ganze Array mit den 21 Nachrichten durchgelaufen ist.
Viel Spass beim Nachvollziehen - wenn ich keine groben Fehler gemacht habe und ich Deinen Flow einigermassen verstanden habe, sollte dann meine Optimierung funktionieren.

node.send zu nutzen, sollte man vermeiden und lieber return msg verwenden. Warum manche meinen sie wollen jetzt node.send verwenden, weiß ich nicht. node.send sollte man nur bei asynchroner Verarbeitung nutzen und dann auch mit node.done abschließen. Also sollte das immer der Sonderfall sein.
Hier ein Auszug aus der Online Doku. Was sonst nämlich passieren kann ist, dass die function Node noch weiter wurschtelt und der Flow hinten dran schon munter weiter läuft.
Bei Dir machte das zwar nichts aus, da es der letzte Befehl ist, aber muss ja nicht sein, wenn man mit return msg die function Node korrekt beenden kann.
Fazit aus dem Ganzen: Funktioniert eigentlich wie es soll - nur sollte man warten, bis ein Gerät auch alle Anfragen bearbeiten konnte und deshalb wartet bis die Getter Node wieder aufnahmefähig sind.
Den Rechtschreibfehler in der ChangeNode mit Read Modubis statt Read Modbus im Namen der Change NOde möge man mir verzeihen, deswegen exportiere ich nicht wieder alles neu.
EDIT:
Falls das aber mit der einen GETTER Node nicht funktioniert mit dem Trigger und Dein Flow nur funktioniert, weil Du 3 Getter-Nodes hast, dann muss Dein Flow so bleiben, da nur dann die GETTER Nodes parallel arbeiten können. Oder Du setzt wirklich die Delay Node ein. Die Frage ist halt ob der 2. Ausgang der Getter Node wirklich signalisiert, dass sie fertig ist oder nicht. Wie gesagt, ich tu mir bei dem Ganzen halt schwer, weil ich diese Hardware nicht kenne und deshalb auch die Nodes nicht. Aber in jedem Fall denke ich, hab ich ein paar Alternativen aufgezeigt- -
@mickym sagte in Node-Red Modbus mehrere Slave ID´s abfragen:
Mir ist auch nicht klar, warum Dein Array oder Deine Objekte soviele Informationen haben (aber vielleicht ist das nur ein anderer Output), wenn Du dann bei Deinem ReadModbus dann die meisten Informationen wieder wegschmeisst.
Das liegt daran, dass ich diese Daten direkt aus dem Modbus Adapter genommen habe. Aber wie du schon bemerkt hast, sind die meisten Daten irrelevant.
So hier ein paar Optimierungsvorschläge:
Nun wie bekannt, bin ich kein Freund von Codierung und function Nodes, wenn es nicht sein muss. Wenn es also um reine Änderungen der payload geht - solltest Du es in meinen Augen vermeiden - dafür gibts die Change Nodes. Wie sowas geht habe ich Dir in meinem Flow mal gezeigt.
Sehr schöne Idee, diese Change Nodes für sowas zu nutzen!
Als erstes habe ich festgestellt, dass Du in Deiner split Node hier msg.parts eingetragen hast - ich weiß das Feld ist rot - aber Du kannst es ignorieren, weil Du ja kein Objekt aufsplittest, sondern ein Array. Insofern gilt das für Dich gar nicht.
Das kam von ein paar vorherigen Versuchen, das ganze zu splitten, Modbus Abfrage und mit dessen Wert, das ganze wieder zusammenzufügen.
Die 2. Variante entspricht in etwa der, die Du jetzt hast, wobei - da alles gleich ist bis auf die ID - ich diese 3 Flows halt zusammengefasst habe. In dem Fall musst Du wirklich mit einer function Nodes arbeiten, da diese einen Kontext hat, der durch das Array der IDs, durch die Du iterieren willst speichern kann und einen zugrhörigen pointer. Mit jeder payload wird der pointer wieder zurückgesetzt.
Die 2. Variante funktioniert nicht. Ich vermute, dass es daran liegt, dass nun jeder Wert einzeln abgefragt wird und dadurch der Trigger next ID aktiviert wird. Durch mein Abfragen der Namen habe ich das verhindert.
Auch und noch eine kleine Bemerkung:
node.send zu nutzen, sollte man vermeiden und lieber return msg verwenden. Warum manche meinen sie wollen jetzt node.send verwenden, weiß ich nicht. node.send sollte man nur bei asynchroner Verarbeitung nutzen und dann auch mit node.done abschließen.

EDIT:
Es wird mir das topic nicht mitgenommen.
vor dem Read Modbus
Nach dem Read Modbus
-
@malaus Ok das war mein Fehler. Wenn das alles war - ansonsten schau ich gerade - dass man erst wenn sich die id wechselt triggert.
Du musst die Change node im Read Modbus entsprechend ändern, um das topic zu setzen:
Bei Dir war aber der Name auch nicht Bestandteil der payload, sondern im topic:
msg = { topic : msg.name, payload : { 'fc': fc, 'unitid': msg.unitId,//JSON.parse(unitid), 'address': msg._address,//JSON.parse(y.number), 'quantity': 2, 'value': 2 } } -
@mickym ich hätte bei bei dem trigger ein switch benutzt, der Ausschau nach dem letzten Wert hält.
Muss das nicht anders herum sein?
Ich hab ja vor dem Read Modbus ein payload.name
und möchte diese nun als topicDann sollte das doch so aussehen:
Das kommt nach der Änderung zurück:
-
@malaus Nein das sieht nicht andersrum aus. Du musst das Lesen wie es geschrieben ist.
Setze msg.topic auf msg.payload.name. Du willst das topic doch setzen - das vorher gar nicht da war.
Bei mir kommt wenn du die Change Node entsprechend änderst, der Name aus dem ursprünglichen Objekt als payload an:
-
@mickym achso habe das anders herum verstanden.
Aber jetzt geht es! und mit dem Switch funktioniert auch.
Danke!
-
Wie sieht der switch aus? ggf. kannst dann auch eine filter Node nehmen.
-
-
@malaus Na ja - ich verstehe, weil Du sagst das ist das letzte Element in Deinem array. Dann finde ich es intuitiver und besser - wirklich die id als topic zu nehmen und hab mal eine filter Node verwendet. Ich weiss nicht, ob aus dem unteren Teil einfach die Eingangsobjekte durchgereicht werden. Aber dann spart man sich das topic einfach.
Falls also am unteren Ausgang der GETTER Node einfach das Eingangsobjekt durchkommt:
Für mich wäre dann das am saubersten:
